Title:
【発明の名称】プロセス制御システムにおける温度送信器用開センサ診断システム
Document Type and Number:
Japanese Patent JPH11506837
Kind Code:
A
Abstract:
A temperature transmitter in a process control system includes a temperature sensor which senses temperature and provides a sensor output related to sensed temperature. An analog-to-digital converter coupled to the sensor output provides a digitized output related to the sensor output. A microprocessor receives the digitized output, compensates the digitized output and provides a temperature output. Comparison circuitry compares the sensor output to a first threshold and provides an inhibit signal to the microprocessor if the sensor is outside of the first threshold.
